The hardest working character in comics logs a hefty amount of his hours to his time on the Avengers. In addition to his many X-teams, he is currently on both the Avengers and the New Avengers, giving him the opportunity to slash through a bunch of villains and drink a whole lot of beer. While he mostly exists in each group to provide smug and aggressive comments during team meetings, it has become hard to imagine either team without him. Publicly known as a murderous mutant, his time on the Avengers has given him a much-needed dose of positive publicity. But the lesser known reason he was chosen was, as Iron Man said, because normal Avengers do not kill, and Wolverine is willing to go to that place.
